Description

Not only does this hybrid of B. lindleyana, B. 'Nanho Purple', and B. 'Honeycomb' have very low seed set, but Buddleja 'Blue Chip' is one of the most compact buddlejas we have trialed. In the Wisley trials it was #2 in public voting after B. 'Miss Ruby'. The short internodes produce a compact plant that stays at 1-2' tall in the first season, and with an annual rejuvenation, it remains 2-3' tall. Unpruned plants will eventually reach 4' in height. B. 'Blue Chip' is adorned through the summer with short spikes of lavender-blue flowers.
